Rheniite - Sold


Rheniite is a rhenium sulfide, one of only two known species with essential rhenium. The mineral forms where hot gases exhale from an active volcano. Znamensky et al. (2005). Pekov (2007) provides further discovery information. The mineral is structurally related to molybdenite, which explains its foliated habit.

Rheniite here forms a metallic foil on altered volcanic matrix. Coverages to 20 by 15 mm are present. This is a rich example. This specimen was formerly in the Rukin Jelks collection and also carries a Fersman Mineralogicla Museum label.
